I removed the Nietzsche quote on the first page. It seemed to me that it had more to do with Christianity than with morality. I added it under the 20th century section of of the Christianity page, however. It's viewable there if anyone needs it.

Ethics, too, are nothing but reverence for life. That is what gives me the fundamental principle of morality, namely, that good ;consists in maintaining, promoting, and enhancing life, and that destroying, injuring, and limiting life are evil.

Let us with caution indulge the supposition that morality can be maintained without religion. Reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle.
